Evenly spaced waves, forming quite a neat pattern where the asphalt's in good condition? Yes, water does that. They're not vibration waves. Vibration waves would come from someone putting a plank into one end of a swimming pool and them rhythmically dunking it with his foot ... which is a strange sort of hobby for which I hope he uses a clean plank. The waves you're used to seeing on the ocean are wind-blown. The ones on the slope are often seen where water flows down a very smooth, steady slope. I don't know exactly what's going on there. Maybe it's surface tension working on it and maybe it's due to some irregularities in the surface, imperfections in the skin ...Imperfections?Microscopic.... but water flowing like that will ripple up, sometimes rather beautifully.

I recall something similar happening with airflow over smooth aeroplane surfaces and creating drag. A glider company made their gliders so smooth that they had to add a zig-zag-edged bit of plastic to break up that effect and prevent the vortex forming. Apparently, a glider with a zig-zag step in its wing surface has less drag than a nearly-smooth or very-smooth one without the step. They were building the glider "the wrong way round," starting by lining the mould with paint, to get a smoother finish than could ever be achieved by painting a glider they'd already built.

This would suggest it's the absence of irregularities in the surface that causes the ripples in the water, but liquid water isn't gaseous air. Hrm.

I tried to find sources to cite, but "Ripple" and "Slope" are both names of much-photographed places, "glider" is an item of furniture, "zigzag" isn't a useful search term for eliminating furniture and when I looked for "zigzag aircraft design" I got distracted by this:

I'd think the waves would move downhill over the water. The water nearest the concrete or asphalt has the most resistance. Water flows fastest in the middle of a (straight) river and slowest near the bottom and the banks. If you tried to slide a satin sheet down an incline, it might fold up and over and slide over itself if that was easier than staying flat. That could happen with the water, with viscosity and the like introducing a pause where the water that's already "on top" gets going and leaves behind thinner water, like drips falling from a tap one by one.

There is a place near here where I may be able to get video of water doing this "steady ripples" thing. I shall attempt to do so at the weekend, if the weather is suitable for it.

I pondered those 'waves'.I could not explain them.

A woman sitting with me told me, she had noticed similar 'waves' moving down a small river, nearby.

Yes. The universe is made of vibrations.Vibrations tend to set up waves and....

But; Y-O-Y, were there waves in that parking lot?

Stackexchange to the rescue!Unfortunately there is no real answer over there, just some hunches.Most of the time when I see runoff ripples, they're mostly caused by wind (gusts) and are apparently called capillary waves.If the ripples also occur with regular spacing in the absence of wind, I would go with something analogous to vortex streets. It's the only type of 'regular' turbulence/fluid dynamics effect that I know of.

AbstractRain waves are well-organized, geometrically more-or-less perfect asymmetrical waves which are commonly found on smooth gently-sloping surfaces (such as sidewalks and streets) immediately after a rain. Swash-zone ripple marks are made by paired sets of hydraulic jumps on gently-sloping beaches during the arrival of medium-to-long period waves. These hydraulic jump sets are formed, and maintained, during the backwash, rather than during the swash, and therefore appear under conditions superficially similar to those responsible for rain waves: gentle slope, smooth or almost-smooth surface, and gravity flow. Yet the two are markedly different, and almost never co-exist. Rain waves form where discharge is steady and also large enough to produce above the wall layer a discontinuous sheet (moving ripples), but not large enough to close the gaps in the discontinuous sheet. The product of "water depth" and "velocity" (hv) has the smallest possible numerical value. Swash zone hydraulic jumps appear where the discharge is increasing (downslope) and also is too large for the sheet of moving water above the wall layer to break down into discontinuous strips (rain waves). The product "hv" is far above the minimum, perhaps by a factor of 5 to 10. Rain waves, as far as is known, do not deform the sand surface, and therefore do not leave recognizable marks on that surface. The paired hydraulic jumps, formed during the backwash, make (and maintain) swash zone ripple marks, bedding plane features so subtle that even specialists might fail to note them.

Got my celery out of the fridge, broke off a couple stalks, felt something slimy on my thumb, figured it was a little bit of rotting leaf (celery has been in there about a week), absentmindedly tried to rub it off with index finger.

There was a RPi-like computer sitting on top of the router and I decided to plug in a thumb drive, after which the wireless connection on my laptop was all over the place —still a strong signal-to-noise ratio, but the connection speed kepting jumping to anywhere between 1 and 72mbps. And after moving the computer suddenly the connection stabilized.

The server is no longer allowed within 30cm of the router. (at least not with USB peripherals plugged in)

Goddamn are houses expensive. That realization has singlehandedly and drastically reshaped my entire view of the world. It is someone else's world, not mine, and I will be lucky if after a lifetime of soul crushingly hard work and saving I might earn the right to call some tiny part of it mine by shortly before I die, and until them I am a fucking serf merely existing anywhere at all at someone else's pleasure, and so beholden my entire life to the lord of the land that is not and may never be mine.

Go you! Apparently, as I had a massive blood transfusion in the 90s when I fell down some stairs and nearly bled out, it is assumed I am mostly insane bovine. Therefore I no longer save anyones life (directly).

You can use a paintbrush or your finger for a low tech option. I've found that with lots of plants simply rubbing your fingers on the anthers, then on the stigmas will work. Lots of people suggest doing the same thing with a paintbrush, because your finger can damage the stigmas if you aren't careful.

Peaches are neat plants in general -- I hope you get some fruit from them!

Yes. That is a good idea.As soon as it stops raining, I will do.

Last year, I got more than fifty little Nectarines from my little Peach Tree.And; I learned Deer will climb steps for peaches, but not for kale. (me, too)

I think it was FreezeBlade that explained, Why!Why; I took a Peach Seed from my mouth, planted it.And; Now I get little bald Nectarines.

I was a good explanation.I can't remember the details.

It is something like:All Great Danes are Dogs.Not All Dogs are Great Danes.

It may be Time for my yearly explanation.

Stone fruits (cherries, almonds, apricots, peaches, plums, etc.) are not true to seed, much like apples and avocados, they can very wildly from the fruit they came from, depending on the cross pollination. If you want some other varieties on there, you can graft any other stone fruit onto that tree, stone fruit are pretty easy to graft (compared to citrus or avocado). The more you know!

Today I learned that being flat-chested has its benefits. I mean, I've heard or read before that there are certain benefits but of course I didn't really pay much attention to it. But today, as I was shopping for new workout outfits to fill my wardrobe, I saw a busty woman struggling with her options. She needed a whole lot of support to exercise freely but there are also a whole bunch of other boxes she needed to tick. As for me, I just grab what I like, try it on and am good to go.

So yeah, basically I ACCEPTED (is a more accurate term) today that not having big breasts isn't all that bad.
